Astra 1N
Astra 1N is one of the Astra communications satellites owned and operated by SES, launched in 2011 to join Astra 2A, Astra 2B Astra 2D at the Astra 28.2°E orbital slot. The satellite was originally designed to provide digital television and radio broadcast services across Europe from the Astra 19.2°E position, in particular the German, French and Spanish markets, alongside the Astra 1KR, Astra 1L, and Astra 1M satellites already operating there.[1]
However, Astra 1N will initially be positioned at 28.2°E to provide capacity for the UK and Republic of Ireland, including the Sky and Freesat DTH platforms prior to the launch of Astra 2E and Astra 2F to this position in 2012 and 2013.[2]
Astra 1N is the fourth satellite to be built for Astra by Astrium and the 46th SES satellite in orbit. On 24 October 2011, Astra 1N entered commercial service at 28.2°E.[3]
The Astra 1N satellite provides three broadcast beams, each with horizontal and vertical polarisation, across three footprints. The UK spot beam covers the UK and Republic of Ireland with reception on dishes of 45 cm diameter across the whole of the UK, Ireland and Channel Islands with the exception of the extreme north east of Scotland, where a 60 cm dish is required.
The Pan-European Beam 1 provides reception on a 60 cm dish across Western and Central Europe including Sardinia in the south but excluding Finland in the North. Pan-European Beam 2 provides 60 cm dish reception over substantially the same area reaching further north into Scandinavia and east as far as the Baltic States, Russia and the Black Sea but excluding more of the Iberian peninsular, Italy and the Mediterranean.[4]
